Systems and methods for modularization and discretization of real-time robot, telerobot and teleoperation systems using passive, network based control laws. Modules consist of network one-ports and two-ports. Wave variables and position information are passed between modules. The behavior of each module is decomposed into uncoupled linear-time-invariant, and coupled, nonlinear memoryless elements and then are separately discretized. Modular architecture for robotics and teleoperation	Anderson, Robert J.	12/03/1996	US 5581666
A technique for computer vision uses a polygon contour to trace an object. The technique includes rendering a polygon contour superimposed over a first frame of image data. The polygon contour is iteratively refined to more accurately trace the object within the first frame after each iteration. The refinement includes computing image energies along lengths of contour lines of the polygon contour and adjusting positions of the contour lines based at least in part on the image energies. Technique for identifying, tracing, or tracking objects in image data	Anderson, Robert J. , Rothganger, Fredrick	08/28/2012	8,253,802
A tubular thermal sprayed melt containment component for transient containment of molten metal or alloy wherein the tubular member includes a thermal sprayed inner melt-contacting layer for contacting molten metal or alloy to be processed, a thermal sprayed heat-generating layer deposited on the inner layer, and an optional thermal sprayed outer thermal insulating layer. The thermal sprayed heat-generating layer is inductively heated as a susceptor of an induction field or electrical resistively heated by passing electrical current therethrough. The tubular thermal sprayed melt containment component can comprise an elongated melt pour tube of a gas atomization apparatus where the melt pour tube supplies molten material from a crucible to an underlying melt atomization nozzle. Thermal sprayed composite melt containment tubular component and method of making same	Besser, Matthew F. , Terpstra, Robert L. , Sordelet, Daniel J. , Anderson, Iver E.	03/19/2002	US 6358466
A method is disclosed for singulating die from a substrate having a sacrificial layer and one or more device layers, with a retainer being formed in the device layer(s) and anchored to the substrate. Deep Reactive Ion Etching (DRIE) etching of a trench through the substrate from the bottom side defines a shape for each die. A handle wafer is then attached to the bottom side of the substrate, and the sacrificial layer is etched to singulate the die and to form a frame from the retainer and the substrate. The frame and handle wafer, which retain the singulated die in place, can be attached together with a clamp or a clip and to form a package for the singulated die. One or more stops can be formed from the device layer(s) to limit a sliding motion of the singulated die. Die singulation method and package formed thereby	Anderson, Robert C. , Shul, Randy J. , Clews, Peggy J. , Baker, Michael S. , De Boer, Maarten P.	08/07/2012	8,236,611
The invention allows the fabrication of small, dense, highly polished spherical beads of hexagonal ferrites with selected compositions for use in nonreciprocal microwave and mm-wave devices as well as in microwave absorbent or reflective coatings, composites, and the like. A porous, generally spherical bead of hydrous iron oxide is made by a sol-gel process to form a substantially rigid bead having a generally fine crystallite size and correspondingly finely distributed internal porosity. The resulting gel bead is washed and hydrothermally reacted with a soluble alkaline earth salt (typically Ba or Sr) under conditions of elevated temperature and pressure to convert the bead into a mixed hydrous iron-alkaline earth oxide while retaining the generally spherical shape. This mixed oxide bead is then washed, dried, and calcined to produce the desired (BaFe.sub.12 O.sub.19 or SrFe.sub.12 O.sub.19) crystal structure. The calcined bead is then sintered to form a dense bead of the BaFe.sub.12 O.sub.19 and SrFe.sub.12 O.sub.19 phase suitable for polishing and incorporation into various microwave devices and components. Method for preparing spherical ferrite beads and use thereof	Lauf, Robert J. , Anderson, Kimberly K. , Montgomery, Frederick C. , Collins, Jack L.	01/01/2002	US 6492016
Method and apparatus for highly polarizing a fast beam of particles by collisional pumping, including generating a fast beam of particles, and also generating a thick electron-spin-polarized medium positioned as a target for the beam. The target is made sufficiently thick to allow the beam to interact with the medium to produce collisional pumping whereby the beam becomes highly polarized. Polarization of fast particle beams by collisional pumping	Stearns, J. Warren , Kaplan, Selig N. , Pyle, Robert V. , Anderson, L. Wilmer , Ruby, Lawrence , Schlachter, Alfred S.	01/01/1988	US 4724117
A one-piece, composite open-bottom casting mold with integral withdrawal section is fabricated by thermal spraying of materials compatible with and used for the continuous casting of shaped products of reactive metals and alloys such as, for example, titanium and its alloys or for the gas atomization thereof. One-piece, composite crucible with integral withdrawal/discharge section	Besser, Matthew , Terpstra, Robert L. , Sordelet, Daniel J. , Anderson, Iver E. , Hartman, Alan D. , Argetsinger, Edward R. , Hansen, Jeffrey S. , Paige, Jack I. , Turner, Paul C.	07/30/2002	US 6425504
